Given numbers are 946, 129, 644, 675

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(946, 129) = 2838

GCD(946, 129) = ( 946 x 129 ) / 2838

= 946 / 129

= 946

Step2:

LCM(43, 644) = 27692

GCD(43, 644) = ( 43 x 644 ) / 27692

= 43 / 644

= 43

Step3:

LCM(1, 675) = 675

GCD(1, 675) = ( 1 x 675 ) / 675

= 1 / 675

= 1

So, Greatest Common Divisor of 946, 129, 644, 675 is 1
